METHODOF INCRUSTING AND IMPRESSING venious MATERIALS.

pressing Various Materials, of which the following is a specification.

My invention relates to a new method for incrusting, inlayingor impressing a suitable material in another material or in a similar inaterial for the purpose of ornamenting this latter material.

.Thisnew method .can be used in order to secure incrustations of a given metal or material in another metal or material, or impressions, in such other metal or material whenthe material which has been incrusted can be easily removed or destroyed after the operation.

My invention has for its pur ose to avoid all the inconveniences of t e methods without necessitating any retouching 0r correcting of the design after it has been in crusted.

In order to have my invention fully understood and to show some of its numerous applications, I will describe the same fully hereinafter, reference being made to the annexed drawing in which:

Figure 1 is a diagrammatic view, partly in section, showing the principal parts or elements of an apparatus necessary to effect the incrustation by direct pressure, in accordance with my invention.

Fig. 2 shows, as an example, a piece of lace which is to be incrusted in a metal plate, according to my invention, in order to give an impression of its design.

Fig. 3 shows a further combination of two metals.

According to my new method, use is made of a press such as diagrammatically shown in Fig. 1 but before placing the plate It upon the pressure block is carried by the piston f, a base m, of relatively compressible material, is placed upon said pressure block 7:). Then, the plate h, carrying the design, monogram, or other figure g which is to be incrusted, is placed upon the pressure block the second pressure block Z is Specification of Letters Patent.

Application filed December 13, 1916. Serial No. 136,822.

then placed upon these elements and finally the necessary pressure is exerted by aid of the pistons f and c. In these conditions, the design or figure 9 which must be incrusted, resting upon the surface of plate ii is the first acted upon by the pressure and drivesbefore it the .IIIGtillOf plate h, thus lengthening the metal of said plate.

This metal is thus pressed into the base m in such a manner that when the incrusted plate 9 is flush with the plate h, thislatter shows the aspect indicated in :Fig. 1, the central partn being located in .the base m which has been compressed accordingly.

Experience has shown that the above constatations are true whatever .may be the complication of the design whichis to be incrusted; the design or figure g is incrusted with the greatest perfection, without .any appreciable deformation and appears in relief on the lower face of plate h; and the design is simultaneously impressed in the base m in such a manner that said base can be used, in several cases, as amatrix for the.

reproduction of the same design orfigurein relief.

In practice, the compressible base at may be a simple sheet of board, having say from eight to ten millimeters of thickness or more; the said base could however be formed of any other suitable material such as, for example, leather wood, India-rubber .or-the like. Thepressuremay be varied in very broad limits and canbelbroughtto very high values such for example as 2000 to 5000 kgs., ormore, on the .quadrate centimeter.

The-perfection of the incrustations thus obtained, gives to the invention a very large field of application.

As an example, it is possible, when operating as above described, to incrust in a metal plate any lace, veil or other fabric so as to obtain after destruction or removal of the fabric, a very true impression of the design of said fabric.

Fig. 2 shows as an example a design of lace such as can be incrusted for example in a copper plate with a view of ornamenting wainscots or the like. The impression thus obtained reproduces all the threads of the lace with a perfection which could not be obtained by any other method.

The effects which are produced by such an impression may be further varied by in- 1 Fig. 3 shows another application of'the' new method to the combination of two metals; in this example, it has beensupposed that a brass plate 7", cut so as'to form a lattice, has been incrusted into a copper plate 8; under the actionof the pressure, the cop per of plates is forced backto the places 7 ofiering the lower resistance'and raises consequently in the hollow partst of the lattice thus producing a kind of padding effect. This kind of application can be used for instance for the manufacture of firm plates in which the letters appear in a metal different from the metal forming the base of the 7 plate; Inthis case the word, design or figmaterial, an impression of said design; or-- figure having a high degree'zof perfection, V

ure to be'incrustediacts, so to say, as a stamping matrix with this difference how-'- ever that 'thls matrlx, instead of bemg'in' steel and very expensive, is formed by 'an ObJBGt which can be very-easily'manufacturedfor instance by means of single saw cuts;

When themethod described is applied to the incrustation of a metal in anothermetal the definitive adherents can be produced by any suitable well known method of soldering, riveting or the like. i V

l/Vhen the twoi-materials which are to be treated by the action of the pressure are different, for instance in the case of board, leather, Wood or v,anv other material in which incrustations or impressions must be effected, this adherence can be secured by cementing, pasting, riveting or any other suitable method. When the design or figure to be incrusted is metallic, it isfrequently fixed directly in the surface whichiis to be ornamented by the operation of'pressure' itself; if it is composed of aifibrous ma-,

terial, such as a piece'of lace, it may be easily 7 removed or destroyed after the operation of incrustation giving then in the; surface of the plate, either of metal, wood or anyother forced into the base which could not be obtained by engraving or with the a1d of punohers, gravers or matrices.

The above described applications areob- "viously only to be considered as examples adapted tofshow the principal results secured by theinvention and-it muster-he understood that my said invention is not re stricted to these examples of applications, other effects or results being also obtainable provided use is made of a compressible base in combinationrwith the metals or--other niaplacing a sheet of flat deformable material upon a flat base .,of compressible materiah' then placing a bo'dy of soft'material' to be incrusted or impressed,icut 'or shaped tothe desired design, upon said-"sheet so that it 'will project above the surface thereof, and
